I presume the question is asking which part of the terminal (ie. to get to which gates) these scanners are used, and possibly even the location within security (left, middle, right) they are located.
I'm presuming this because this was also my initial question when I heard about the introduction of these scanners, as if there's only one at the end of ten or so normal metal detectors then it may be possible to avoid the random lottery by going through an area of security far away from the scanners.
However, as I've found out at SFO several times now, it doesn't appear to be possible to avoid them unless it is particularly busy, as they seem to close down the other 'aisles' when not busy in order to steer you all towards the scanners. On two occasions now, my girlfriend has been directed through the normal metal detector, while I was directed to the scanner, and promptly opted out.
I'd be interested in hearing what the best arguments for opting out are, as medical (I used this when they were first introduced) and privacy reasons have both gotten snarky remarks/discussions from the security staff (maybe another question for this though)

As of July 2016, there are millimeter wave detectors at every single security lane in Pierre-Elliot-Trudeau airport.
However, you can choose to get patted down instead of going through the scanner. Simply ask the staff before going through.
